What is 99 Nights in the Forest?

99 Nights in the Forest is a survival horror game on the Roblox platform, developed by Grandma’s Favourite Games . In it, players must survive for 99 nights in a forest full of dangers (hostile creatures, cultists, supernatural creatures), collecting resources, building shelters and rescuing lost children while facing increasing threats.

The game also incorporates a code mechanic that allows players to receive free gems (diamonds), which help unlock classes or purchase upgrades. At the time of this guide, the code system is fairly new, with only a few active entries.

Why use codes?

Codes are promotional incentives that the developer occasionally distributes to reward the community. Redeeming them typically gives you free gems (diamonds), which can give you a head start when unlocking classes, items, or talents without spending Robux.

Plus, these codes often have limited validity, so it’s important to use them as soon as possible. Here’s how to stay up to date and which ones are active right now.

List of active codes

At this time, the community has verified the following active codes for 99 Nights in the Forest:

Code Reward Status / Notes afterparty 15 gems / diamonds Active — just released with the “Volcano Part 2” update

How to redeem codes step by step

To avoid getting lost when trying to redeem a code, follow this step-by-step guide:

1. Launch Roblox and open 99 Nights in the Forest .
2. Locate the main lobby of the game (before entering the game).
3. Click on the gems/diamonds icon that appears in the lower left corner.
4. Within the gem menu, you should see a button that says “Codes.”
5. Click on “Codes” and a text field “Enter Code” will appear.
6. Enter the code exactly as it appears (for example, `afterparty`).
7. Press “Submit.” If the code is valid and active, you’ll receive the gems instantly.
8. If it doesn’t work, check that there are no extra spaces, that it has expired, or that you have already used it.
9. If you experience an error, please restart the game or change servers and try again.

Recommendation: Enter the code immediately after it is released, as many codes have an expiration date or limited use.

Tips to avoid losing codes and stay up to date

• Join the game’s official Discord server – developers often announce codes there first.
• Follow the official Roblox group/account related to 99 Nights in the Forest .
• Check out the developers’ social media or official channels — some code is created as part of events or patches.
• Visit community wikis, forums, or dedicated game blogs—they often update quickly with new codes.
• When you see a new code, use it immediately — some expire in hours.
• Avoid generators or third-party sites that promise free codes — some may be scams or phishing.
• Take screenshots or keep a record of the codes used to avoid duplicates.

Other ways to get gems in 99 Nights in the Forest

Codes aren’t the only way to get gems in this game. Here are alternative methods you can combine with codes to maximize your resources:

• Overcome nights and progress

As you progress and survive successive nights, the game awards gems at certain milestones. For example, when you reach night 50 and night 99, you get additional gems.

• Complete game badges

There are achievements (badges) that award gems upon completion. These can include tasks such as surviving under special conditions, improving fire, performing secret actions, or completing challenges within the forest.

• Open chests during the game

Within matches, some chests (Good, Iron, Ice, Gold, Legendary) may contain gems, albeit in small quantities. By exploring the map and opening chests frequently, you accumulate extras.

• Special events or “Update Party”

During updates or events, developers may activate special matches where administrators place gems within the map to reward players who participate.

• Purchase with Robux (premium option)

If you’re willing to invest, you can also purchase gems with Robux in the lobby currency store. But for many players, free methods are sufficient if combined well.

Common mistakes and how to fix them

Players sometimes encounter issues when trying to redeem codes or claim rewards. Here are solutions to common errors:

The code doesn’t work / “Invalid code”

• Check that you wrote it exactly, without extra spaces.
• Make sure the code has not expired.
• Please restart the game or change servers and try again.

You already redeemed it

Some codes are for one use only per account. If you’ve already used one, you won’t be able to claim it again.

Gems do not appear after redeeming

It could be a visual delay. Close and reopen the interface, or even exit the game and re-enter it to make them appear.

You don’t see the “Codes” button in your game

This may be because the code system isn’t yet rolled out to all servers or regions. In that case, update your game, wait for a patch, or check if your lobby is the latest version.

Upcoming expected codes and predictions

Since the code system has only recently been implemented, many predictions revolve around major events and updates. Here are some ideas of what to expect:

• When there is a new major patch (e.g., “Volcano Part 3” biome expansion or others), they will likely release celebration codes.
• Codes for game anniversaries (months since release) are often common.
• Themed events (Halloween, festivals, special missions) may be accompanied by temporary codes.
• Balance updates or bug fixes may come with “compensation” via community codes.

My recommendation: whenever there’s an official announcement or major update, check the developer’s social media and be among the first to redeem.

Quick checklist for using new codes

As a helpful summary, here’s a quick checklist for when you discover a new code:

• Read the code and copy it accurately (without spaces).
• Enter the game lobby as soon as possible.
• Go to the gems/diamonds menu → Codes → enter the code → Submit.
• Confirm that the reward has been added.
• If it doesn’t appear, close the game or change the server and try again.
• Save a screenshot or note of the code for future reference.
• Check expiration dates to ensure you don’t miss out.
